What is a QR Code Generator?
A QR code (Quick Response code) is a two-dimensional barcode that smartphones can scan to open a URL, dial a phone number, draft an email, start a WhatsApp chat, open a payment link, or show plain text. They work offline as encoded data, with no account or redirect service required.
Ozaar QR Code Generator supports five types: URL/Text, Phone, Email, WhatsApp, and Payment link. Fill in the fields for the type you need and the code updates as you type. Download as PNG for screens or SVG for print, with custom colours and sizes, and no watermark.
Everything runs in your browser. Sensitive numbers, emails, and payment URLs never leave your device.
How does QR Code Generator work?
Each QR type builds the right payload automatically: tel: for phone, mailto: for email (with optional subject and body), wa.me for WhatsApp (with optional message), and a direct URL for websites or payment links. The qrcode.js library then encodes that string with Reed-Solomon error correction and renders PNG and SVG.
Error correction means codes can still scan even if part of the printed image is damaged. Because we do not wrap your content in a tracking redirect, the QR works permanently as long as the destination itself remains valid.
Why use a browser-based QR Code Generator?
Browser-based generation is fast and private. There is no server round-trip, and internal links or private contact details stay on your device.
Unlike many QR services, we do not create redirect URLs. No tracking of scans, no expiry from our side, and no dependency on our servers after you download the file.
You might also want to compress your downloaded QR images or resize the QR image for specific use cases using our free browser tools.
